Application filed'March' 29,1910. Serial No. 552,197.

To all whom it may concern:

Be it known that I, JAMEs H. BOBBITT, a citizen of the United States,and a resident of Holstein, in the county of Adams and State ofNebraska, have invented a new and Improved Sash-Fastener, of which thefollowing is a full, clear, and exact description.

My invention relates to sash fasteners, and has for an object to providea device of the above class to removably engage the sash of a window orthe like to hold the same in a locked position. For the purposementioned use is made of a rack mounted on a collar in engagement with aspindle, and means engaging the spindle for removably holding thespindle in a locked position to engage the rack with the sash of awindow, to hold the same stationary.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which- Figure 1 is a sideelevation of a portion of my device showing the rack andspringcontrolled collar with the rack in its initial position; Fig. 2 isa similar view but showing the rack in a position whereby it is adaptedto engage the sash of a window; Fig. 3 is a front view of my deviceshowing the rack and easing; Fig. 4 is a rear view of the same; Fig. 5is a sectional plan view disclosing my device in operative position; andFig. 6 is a sectional side view of the dog and rack for removablylocking the spindle, and taken on the line 66 in Fig. 5.

Referring more particularly to the various figures, I employ a casing 1,having a front plate 2 and side plates 3, having mounted thereon acollar 4, comprising a lug member 5 and an arm member 6. Mounted on thearm member 6 is a rack 7 comprising a curved member having a series ofserrations 8 thereon, the rack 7 being mounted to slide against a lug 9secured to the side plates 3. A fiat spring 10 is provided secured tothe casing 1 and adapted to en age the lug 5, as will be easily seen byreferring to Figs. 1 and 2. The collar 4 is provided with a rectangularhole 11 through which is adapted to pass a spindle 12 having acontrolling knob 13 secured thereon, the said spindle being mounted toturn in a window casing 14 of a window 15, having a sash 16, and

seen by referring to Fig. 5. Intermediate the knob 13 and the windowcasing 14 is a circular casing 17 secured to the window casing 14.Centrally mounted in the casing 17 is a ratchet 18 keyed to the spindle12, and a dog 19 having a knurled handle 20 is provided in the casing 17and mounted to engage the ratchet 18, a spring 21 being secured to thecasing 17 and engaging a lug 22 on the dog 19, to hold the dog 19 inengagement with the ratchet 18.

To operate my device to removably engage the sash of a window, to holdthe same in locked position, the window is raised or lowered to thedesired height and the knurled handle 13 is turned to move the collar 4downward, so that the rack 7 will engage the sash 16, and the dog 19engaging the ratchet 18 securely holds the spindle 12, so that it cannot turn backward and release the sash 16 from the rack 7. Now when itis desired to release the sash, the dog 19 is first drawn out ofengagement with the ratchet 18, and then by turning the knob 13 the rack7 will move upwardly and out of engagement with the sash 16, therebyenabling the window to be moved.

It will be seen that my device can be mounted to act on either the upperor lower sash, or can be so mounted in the window casing that the rack 7will engage the upper and lower sashes at the same time.

In order to provide a neat appearing de vice, the knob 13 can beartistically decorated in various designs; and the casing 17 can be madeto lie flush with the window casing, or as shown in Fig. 5.

It will be understood that although I have shown a particularconstruction. for the pur pose of describing my invention, I do notlimit myself thereto, the scope of my invention being fully defined inthe appended claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A sash fastener comprising a spindle, a collar secured to thespindle, an arm extended from the collar, a rack mounted to swing on thearm, a lug on the said collar, and a spring engaging the said lug, forholdmg said rack in operative position.

2. A sash fastener comprising a spindle, a In testimony whereof I havesigned my collar secured to the spindle, an arm exname to thisspecification in the presence of 10 tended from the collafr, a serratedrack two subscribing witnesses. mounted to depend rom the arm and w 5adapted to swing thereon, a lug on the said JAMES HOMER BOBBITrl collar,and a flat spring engaging the said \V'itnesses: lug, for holding thesaid rack in operative JOHN H.
